DEMOUNTABLE-BJM DISK WHEEL.

Application led August 4, 1920. Serial No. 401,107.

l -l To all whom t may concern.'

Be it known that I, WILLIAM ERAsrUs -WI-LLIAMS, a citizen of the United States, a

resident of Chicago, in the county of Cook and State of Illinois, have invented a new and useful lmprovement in Demountable- Rim Disk Vlheels, of which the following is a specification.`

My invention relates to disk wheels, for automobiles, using pneumatic tires carried by a rim which can be attached to or removed from a elloe.

'lhe object of the invention is to provide a very light, cheaply constructed, disk wheel body that may be securely fastened to a felloe, and that o'ers great resistance to both tension and compression. y Y; Reference will be had to the accompany` ing drawing in which Figure 1 is a iront elevation of the wheel.

Figure 2 is a side sectional elevation.

Figure 3 is a sectional detail oi a part of v the rim.

ln the drawing 1 indicates an ordinary demountable rim for a pneumatic tire. 2 an ordinary hub, 3 a brake drum, l a steel lelloe, 5 theV inner of two disks forming the wheel web, 6 the `outer disk, 7 clip bolts, 8 demounting clips, amd 9 the clamping wedge ring ordinaril employed with des c mountable rims ci this' typeI 10 designates aV rear hubdlange, 4here shown as integral, 11 a iront clamping liange, and 12 bolts clamping together the drum and anges. The tlangesliave on their inside, opposing, laces lsinuous marginal groei-ves which pass alternately inside and outside the holes for consecutive bolts, 'lhe disks 5, G have like sinuous internal grooves and corresponding external ribs which tit in the disk grooves, respectively, where they 'are held by a correspondingly sinueus ring or tube i3 between 'the disks.i

sks .are provided, radially outside the @anges il), ll, with annular swells 15,-`

lli which girV the disks, as a whole., slight elasticity and the same time stiden the portions the danges 10, 11 and prevent'` movement at this point. 'lhe sinuous construction. secures the disks to the lmb in such manner thatthe union has approximately as great resistance to vboth tensile and compremive strains as the body oi' the dis 1ra.

The metal ori the disks entends beyond the i point terminates 'lier down i ave to be stretched or compressed in order to accommodate the variations in the circumference due to larger or smaller diameters.

The margins of the disks 5 and 6 'are turned over the front flange 17 of the felloe as is indicated by 18 and the wedge ring 9 bears on the margins of the disks holding them ndown on to the front lange 17 on the surface 19. The bodies .of the disks are curved under the inside front corner of the felloe as is indicated by 20 arid the lower or inner edges 21 of the clamping blocks 8 bear directly on to the body of the disks opposite the inside corner 28 of the felloe 4. rlhe inside flange of the elloe is indicated by22 and it is provided with a turned over edge 23 for furnishing the bearing' on the inside fortherim 1.

The edges of the disks where they turn over the iront flan e 17 oi' the felloe are riveted or spot wel ed through this flange 17 as is indicated by 2li and thus the metal of the disks is held against being withdrawn over the edge ol the flange 17 of the elloe.

The central load line of the wheel is indicated by 25 and this load line is liked by the normal arrangement of a wooden wheel. The location o=the Hangs `10 of the hub is substantially the same location of the inside of the zone ofthe spokes ci a normal wooden wheel assembly.

The' greatest shocks that wheels are exposed to are skid shocks rather than rolling load shocks and hence is most desirable to provide adequate strength for skid shocks avoiding unnecessary weight oi material.

The connection oi: disks with the front vedge of the elloe 4; as is indicated` furnishes ample direct loadr carrying capacity and at the same time gives a greater skid shock resistance than might be the case where the disks fasten to the felice near the load line 2t, the separation of the disks at the hub and. their association at the rim being the This l lil() `isa mitted through the fastening of the disks to the felloe'parts so that the amount of load that is necessarily carried through the fastening of the disks with the felloe may be said to be representedby what is carried by the flange 22 of the felloe 4 or the inside flange of the felloe. This flange 22 is deepel than the flange- 17 and taken in connection with the body of the felloe l is amply strong to transmit the Whole load without any appreciable distortion so that the felloe thus connected with my disks operates almost as a unitary structure might act.

The sinuous fastening of the disks to the hub flanges as indicated by the grooves 14 allows the pressure of the clamping bolts 12 to be approximately uniformly distributed to the ring or spreader 13 and at the same time makes a positive fastening against the rotation of the disks" in relation to the hub flan es. This sinuous of t e hub being curve ermits the slot to be milled in a turning athe having a tool post movement under the influence of a cam, which permits the machining of said groove with little or no expense more than is occasioned with a uni'- form circle groove. The fasteningY of the disks to the hub flanges at the margins of the latter distributes strains on the circumferences of circles much larger than the hub barrel where fastening is more commonly made and so gives much greater strength, the resisting metal being greatly increased in cross sectional area.

The rearintefrral flan e 10 of the hub is reinforced by fller bloc s 26 and for the purpose of lightening the material there are apertures 27 in this rear flange between the filler blocks 26. These apertures are vcovered over by the body of the brake drum as shown.

The front disk being curved outward and over the front edge of the felloe, makes a perfectly smooth clean arrangement for washing theV wheelon the front face, which reat desideratum. at I claim is 1. In devices of the class described, the combination with a felloe of outwardly open channel form, of a Wheel body of the disk type having its eripheral zone bent laterally over and c osely fitting one flange of rooye in the flanges in outline as shown` the felloe, a rim encircling said flan e, a wedge interposed between the rim and ange and resting against the inwardl bent zone, and means for urging the we e inward.

2. The-combinat1on with a fe loe in the form of an outwardly open channel, of companion wheel disks forming marginally a double web and bent to ether closely around the margin of one of t e felloe flanges and in contact with both faces of the same.

3. The combination with a metal felloe having in radial cross section the form of an outwardly open channel, of a wheel body of the disk type having its peripheral' zone fitting against one face of the felloe flange, doubled back closely around the flange edge and inwardly along the opposite face, a rim encircling the felloe, 'blocks for rigidly clamping the felloe and rim relatively, and bolts for exerting the clamping force.

4. A metal felloe of outwardly-open channel shape in radial section, wheel disks having theirouter zonesin lateral contact and doubled back over the edge of the felloe flange into the channel to form with the flange, in radial section, a compound web, and means for securing the disks and felloe against relative movement.

5. In a vwheel of the class described, a felloe, a plurality of disks forming the web of the wheel, said disks Vinseparably secured to each other and to the front side of the felloe and .diverging in passing inwardly from the rim, a rim encircling the felloe, bolts passing through the felloe and disks, and a wedgin T device ur ed by the bolts into position or ri idlyy olding the rim, felloe, and disks a alnst relative movement.

6. The combination with a felloe, of wheel body disks resting against the front side of the felloe and bent laterall inward at each margin thereof, clamping evices fitting the inwardly bent ortions at the felloe margins, and bolts inding said devices to the felloe.
